Multi dimensional force sensors need to be calibrated before use

Multi dimensional force sensors need to be calibrated before use

1. A small "baffle" should be installed in the surrounding area, and even a thin metal plate should be used to cover the multidimensional force sensor. If it is allowed to prevent debris from contaminating the sensor and certain active sides, this "contamination" often makes the active side uncomfortable and affects the weighing accuracy.

2. All wires entering and exiting the display circuit should be shielded cables, and the connection and address of the shielded wires should be reasonable. If it is not grounded through the mechanical frame, it will be grounded externally, but the shielding wires will not be grounded and suspended after being connected to each other.

Note: There are parallel 3D force sensors available. The force sensor itself is a 4-wire system, but it is replaced with a 6-wire connection in the junction box. The sensor output optical signal readout circuit should not be placed in a unified cabinet with equipment that can generate strong interference and considerable heat. If it cannot be guaranteed, consideration should be given to installing baffles between them to isolate them and place them in the cabinet. The body is equipped with an electric fan, and the electronic components used to measure the output signal of the force sensor are clear. It should be equipped with a self powered transformer as much as possible, rather than sharing a unified main power supply with equipment such as contactors.

3. Multi dimensional force sensors should use hinge copper wires (with a cross-sectional area of approximately 50mm2) to form an electrical bypass to protect them from the risks of welding currents or lightning strikes. During application, strong thermal radiation, especially on one side, should be avoided.

4. For electrical connections such as optical cables for force sensors, the strong power or control lines on the back should be arranged in parallel (for example, do not place the light, strong power, and control lines of the force sensor in a unified pipeline). If they must be placed in parallel, the space between them should be kept at least 50cm, and the optical signal lines should be covered with metal pipes.

5. Although advantageous layout accessories such as spherical bearings, connecting rod bearings, positioning fasteners, etc. are used for automatic positioning (reset), they can prevent certain lateral forces from being beneficial to the sensor. It should be noted that some lateral forces are not caused by mechanical arrangements, such as lateral forces caused by thermal expansion winds and lateral forces caused by vibration of agitators on some container weighing instruments, which are not caused by mechanical arrangements.
